PHOTODIODE
InGaAs PIN photodiode with preamp
G9821 series
Receptacle type, 1.3/1.55 µm, 2.5 Gbps
G9821 series is a family of high-speed receivers specifically developed for 1.3/1.55 µm band optical fiber communications. These
devices incorporate a high-speed, high-sensitivity InGaAs PIN photodiode and a high-speed preamp integrated in a receptacle module.
Packages are available with various connectors and mounting styles.
